Advancing hydrogen-electric aviation in Europe

TRIATHLON highlights two years of progress toward integrated propulsion technologies

At its Month 24 milestone, the TRIATHLON project reports significant progress in the development of hydrogen-electric propulsion technologies for aviation.

“We are at the halfway point of the TRIATHLON project, and all the separate building blocks are starting to come together.” — Dr.ir. Julien van Campen, Project Coordinator

Over the past two years, the project has advanced key components across hydrogen combustion, storage, thermal management, and full powertrain integration. These results demonstrate how different technologies can be developed and evaluated together within realistic aircraft constraints.

By combining component-level innovation with system-level modelling, TRIATHLON is contributing to the technical foundations needed for future low-emission aviation.

The full press release, including detailed results from each work package, is available below.
